[feature] Support for binary buffers in loadImage

Hi. I don’t know if it’s possible to add support for buffers in loadImage or some new function. I’ve looked through the code and it seems that files reading is handled inside dlib and I didn’t find any easy way to do a quick PR.

This feature could be utilized in cases when images are stored not on disk (so previously you will get them from somewhere) or images could be preprocessed. So, in this case, they will be loaded into memory as Buffer and storing them to disk and then performing cleanup will add unnecessary overhead.

@justadudewhohacks, thanks. I just used pure opencv4nodejs and CascadeClassifier. And it worked with buffers. And face-recognition.js face detector seems working much slower than opencv’s. So anyway the last solution satisfied all my needs.

As I said, I’ve looked through dlib sources and didn’t find a way to use buffers, just thought maybe I’ve missed something.

Thanks for help.

Ok. Yes face detection with opencv is way faster but not as stable. If that’s applicable for you and don’t need face recognition, then I would stick with opencv4nodejs.
